Personal Jurisdiction Over Online and Foreign Defendants: From Zippo to Ford Motor

A company in Shenzhen sells 40 units into Illinois through a marketplace. A blogger in Ireland writes something defamatory about a California executive. A German manufacturer sells components to an American assembler who ships finished products everywhere. In each case the threshold question is the same and is genuinely hard: may a United States court exercise power over this defendant. This article explains the modern doctrine of personal jurisdiction as it applies to online and foreign defendants, beginning with the constitutional framework of International Shoe and the sharp separation of general and specific jurisdiction that the Supreme Court has enforced since Goodyear and Daimler. It covers the effects test of Calder as narrowed by Walden, the Zippo sliding scale for websites and why most circuits have moved past it, the express aiming and something more standards that replaced it, the meaning of Ford Motor's holding that a claim may arise out of or relate to forum contacts without strict causation, and Mallory's revival of consent by corporate registration. It then addresses the machinery: state long-arm statutes, the federal long-arm of Rule 4(k)(2), jurisdictional discovery, waiver under Rule 12, and the practicalities of suing defendants abroad. It closes with strategy for plaintiffs and defendants, a worked example, an FAQ, and related reading.
